For wavelength division multiplexing (WDM) technology the preference is given to the erbium-doped optical fiber amplifiers (EDFAs). EDFA working principle is based on optical signal amplification using stimulated emission in the fibers with a small controlled amount of erbium added to SiO2 in the form of Er3+ ion. Erbium doped fibers (EDF) typically have smaller core size than standard ITU-T G.652 fiber to achieve single mode propagation at both: pump wavelength at 980nm and amplification range from 1525 to 1565 nm. Because of smaller core size optical radiation intensity in such a fiber is higher and can cause nonlinear optical effects (NOE) appearance.
